When I was still at Western, I did this demo for the Fire Protection Associate Degree Students enrichment Saturday for their Club. I did it in a hood, behind a explosion shield, and it helped the fire protection trainees to see the vapor trail and get the idea of how the vapor can travel and ignite. I thought it was a worthwhile demo for that population, and it went over well. I did not perform it exactly as explained in the kit, because I was not convinced of the safety of their method.

I have the kit and can send the instructions if the group would like. Don't remember why, but my demo students ended up not using it.

Perhaps DCHAS should buy the kit and read the directions.

This is what I did with their rainbow colors demo kit .... deficient. ... Jim

Hey Monique - What is the kit called?

Perhaps that teacher might read, "Playing with Fire, Chemical Safety Expertise Required"?

Duh...

It saw this too. It made me wonder if the approach we, the ACS, is taking is the correct approach. In addition to teaching the safe way to show the demonstration we need to discover where this teacher learned how to do this demonstration, follow the trail back to get to the source of the demonstration and correct the problem.

Hi All,

Here we go again. Another flammable demonstration gone wrong.

This was reported on ABC National News tonight (Nov 2).. It happened in Georgia this week.

Fortunately, the teacher was not seriously injured (minor burns and burned hair) and none of the students were hurt. One very, very lucky teacher!

I guess she was trying to show that flame will follow a vapor or that the vapor had a higher density than air.
